Answer:

Both proportions are equivalent.

Step-by-step explanation:

We have been given two proportions \frac{40}{8}=\frac{x}{10} and \frac{x}{40}=\frac{10}{8}. We are asked to find why the solutions to our given proportions are equal.

We can solve proportions by cross multiplying them.

After cross multiplying our both proportions we will get same equation that is:

40*10=8*x

400=8x

8*x=40*10

8x=400

Since we get same equation after cross multiplying both proportions, therefore, the solutions to the given proportions would be same.

Given below are the coordinates of the vertices of a triangle. Find the lengths of the sides of the triangle, then click to iden
Vsevolod [243]
The length of a segment, given the extremities, is:
√[(x₂ - x₁)² + (y₂ - y₁)²]

Therefore:

RS = √[(3-1)² + (1-3)²] = √(4+4) = √8

RT = √[(5-1)² + (2-3)²] = √(16+1) = √17

ST = √[(5-3)² + (2-1)²] = √(4+1) = √5

Since the lengths are all different, the triangle is scalene.

Solve the equation x2+11x-15=0, give ans to two dp.
Charra [1.4K]
Im going to assume you know the formula.
sooo.
x= -11 +- √ (11)² -4 (1) (-15)
     --------------------------------- 
          2(1)

= -11 +- √121- (-60)
  -------------------------
              2

= -11 +- √181
   -----------------
            2

= -11 +- 13.45
   -----------------
             2

Either:                                                Or:
                                                          X = -11 - 13.45
  x = -11 + 13.45                                       ---------------
                                                                        2
       ----- ----------                               
              2       
   x = 1.23                                           x= -12.23
